･Analog power supply
･3-V-A, 3-V-B power supply for digital I/Os
･1.5-V-A internal power supply for the digital logic : DVCC1A & DVSSCOM
･1.5-V-B internal power supply for the digital logic : DVCC1B & DVSSCOM
･1.5-V-C power supply for oscillator

TMP92CF26A is provided with the following six power supply rails.
external pins (DVCC-3A, DVCC-3B), AD converter (AVCC) and RTC and backup RAM
(DVCC-1B). After entering this mode, internal signals that communicate with the circuit blocks
powered by DVCC1A and DVCC1C are cut off so that no shoot-through current is generated in
the circuitry when the power is removed from those blocks.
